HELP!!! is possible TWRP for ULEFONE S8 PRO.

Hi, it would be possible TWRP for ULEFONE S8 PRO, this phone comes with a Trojan in the sound recorder, and is installed in the system part, so if I do not root or install TWRP I can not delete it. If any developer can help us and give us some solution ... I sent several emails to ULEFONE and they do not answer. The Trojan was detected by ESET NOD 32 MOBILE.
Thank you
up! All the tutorial have wrong TWROP too that make the item reboot only to TWRP
root ok
well, after two days trying, root made.
1- flash official rom with sp flash tool and rom downloaded from ulefone.com/download/s8pro.html (do not use flasher from this web, use sp flash tool)
2- download ulefone s8 pro toolkit, put phone in fastboot mode (power+vol up), select fastboot
3- download super su last version from official chainfire web, copy supersu file and noverity.zip from file downloaded in point 2 into an sd card and put into phone.
4- execute ulefone s8 pro toolkit.exe, option 41, connect phone. phone prompt if wish unlock bootloader, vol up for yes. phone reboot into twrp
5- in twrp, first go into wipe-advanced wipe-select data-repair or change file system-change file system->first change to exFAT, second change to EXT4 (the original part type)

Can you link the s8 pro toolkit (even in private message) since the one I have just bootloop TWRP and doesn't allow me to do something...thank you!
Another way to root, but no TWRP is to patch the boot.ini extracted by the firmware zip , patch it with magisk manager and replace the original one with the patched one via ADB.Then you can update magisk by magisk tool everytime, the phone won't brick, just no ways to update....
thank you !

You can only unlock the bootloader for now. As of the time this is being posted there is no known working root for the A21s.

Download the most recent firmware of ur a21s. Unzip your downloaded firmware and you will get 4 tar files. You will need the AP tar archive. Install 7-zip on ur PC. Decompress the AP tar file. Go in the folder in that you decompressed ur tar and archive these files "boot.img,vbmeta.img" in tar. Install the magisk app on ur a21s and push the file from PC to a21s. In magisk select in "magisk" section install then "Select and patch file" and browse and select ur tar with boot.img and vbmeta.img. After patching transfer the file from ur phone to PC, and download odin. Power off your phone and then press volume down and up and insert usb cable. Open odin select AP and browse for ur patched tar. After select ur AP make sure u DON'T chosed nand erase and repartition and press start. The phone will reboot in recovery and u have to do wipe data partition. Before doing these make sure u unlocked the bootloader and make backups. And making this, you will lose ur warranty. BTW there is exist a twrp unofficial recovery that didn't boot loop ur phone to odin mode. If you want to flash the twrp put ur phone to download and in odin chose AP and browse to the twrp tar u downloaded.

merhaba s7'm var artı t970'im var nasıl rootlayacağız
Translation: hello i have s7 plus i have t970 how do we root
I followed this guide below that I found somewhere in this forum, it is not mine, I just added some notes to it. I recommend searching for the original thread. There could also be a newer firmware version now, please check yours before rooting. It has been almost 2 months since I did it.
Unlock OEM (under developer options)
Boot in download mode (with the tablet powered down, press volume up + volume down and connect USB cable to PC)
Long press volume up to unlock bootloader (you will lose all your data!)
Download the original firmware ( https://www.sammobile.com/samsung/galaxy-tab-s7/firmware/SM-T970/XAR/download/T970XXU1ATJ4/502568/ )
Flash it using ODIN in download mode (Optional, just to make sure you are using the same image you are going to patch)
Extract boot.img.lz4 from AP_xxxx tar file.
Decompress the lz4 to get the uncompressed boot.img (I had to use a separate tool since 7zip was not able to compress/uncompress the lz4 archive, https://github.com/lz4/lz4/releases )
Copy the file to the tablet
Patch it using the latest Magisk Manager. ( https://github.com/topjohnwu/Magisk)
Copy the patched boot image back to the PC.
Recompress it as boot.img.tar (rename magisk_patched.img to boot.img then compress as boot.img.tar)
Flash it using AP slot in Odin and reboot tablet. (I had to do a full factory reset)
Install Magisk again
For AdAway to work you will need to enable systemless module in Magisk
You are done! Magisk manager should say now it is rooted. (you will also have a BIG warning every time the tablet is powered on, telling you how irresponsible and despicable you are by modifying the device)
I rooted my Samsung S20 before by following this guide
it is very similar to what is described above.

I have android 11 installed on my device, can you help me with remote team use?

@simerenya Please use English on XDA Forums. If you want, you can use the translating service of your choice. See the forum rules for more details.
@BigBucha I suggest that you do not link to that particular website for Magisk downloads (or any other website that pretends to be the Magisk website). None of those websites are run by @topjohnwu and in the best case they're just re-hosting the files to get ad-revenues, but in the worst case you'll download a malicious version of Magisk. That wouldn't be good. The only place for sure and safe downloads of Magisk is on @topjohnwu's Github: https://github.com/topjohnwu/Magisk
@Didgeridoohan , understood, thanks! I didn't know about Magisk's official web site, just googled it. I updated my previous post.
@simerenya,
Not sure if I understood your question. I used google translate.
You asked for a screen-sharing session?
I have done rooting of this tablet model only once myself, that was 2 months ago, not sure if I can be of much help to you.
Please try following the guide step by step yourself. If in doubt, I recommend not doing this since you may brick your tablet.
You can post your questions in the forum if you get stuck or brick your device. I will try to answer them.
I was able to root my tablet from the first try.
Good luck.
Is it possible to root Galaxy tab s7+ using Kingroot, kingoroot, towelroot, or any of the other 1 click rooting apps?

Thanks for the instruction. I was finally installed magdisk on S7+ tab. Root check is good. But some app like adaway does not detect root and never ask for root access when installed. Do you know how to solve this?

Not sure about other apps, but for AdAway to work I had to do these steps:
1. Open Magisk
2. Go to Modules (the jigsaw icon)
3. Install "Systemless Hosts" module
4. Reboot and try selecting root mode in AdAway again

This apk is old. If you have rooted with this apk/tar, then you should download the latest one from this thread and update to it, as it has the latest patches merged in from official Magisk github.

Hello,
My phone got stuck at the same screen and no button is answering. I also have the U5 version.
How did you manage to recover the phone?
Thank you in advance.

Plug usb to laptop, press and hold all buttons (power, volume up, volume down) for 10 seconds your phone will reboot. Release all buttons, then press and hold volume up and volume down and quickly plug usb to phone, your phone will enter download mod where you can flash stock firmware via odin.
I see references to U3 and U5. I have a SM-A215U. Did you mean 5U and not U5? Also, someone asked above if this wipes your data. I too am wondering the same. Thanks!

Ah thanks. Having trouble finding root instructions for mine, and starting to be somewhat sure they don't exist. So many garbagey sites with bad info. This is the only site I ever see the real deal.
Got my SM-A217F rooted first attempt,
So what i did was.....
1) used Frija-v1.4.4 to download my latest stock firmware "SM-A217F_1_20210807114045_mzeyu27v8u_fac.zip"
2) Extracted the zip file and flashed the 4 files with "Odin3_v3.14.4"
3) after that i let the phone restart and boot up entered my google account details etc etc
4) on PC i used winrar and extracted the "boot.img.lz4" file only from "AP_A217FXXU6CUH1_CL21842546_QB42174009_REV00_user_low_ship_MULTI_CERT_meta_RKEY_OS11.tar.md5"
5) on PC i then used "lz4_win64_v1_9_3" i copied the extracted "boot.img.lz4" file into the "lz4_win64_v1_9_3" folder
6) op PC inside the "lz4_win64_v1_9_3" folder i dragged the "boot.img.lz4" file onto "lz4.exe" wich created a new file "boot.img"
7) copied the "boot.img" file onto my phones internal storage
8) on phone i installed "Magisk_patched_for_A21S.apk" and opened it --> chose "Install" -->"select and patch a file" --> select "boot.img" from step 7 --> normal android way
9) That created a "magisk_patched-22104_0x2Ov.img" file in my phones "download" folder
10) Renamed that "magisk_patched-22104_0x2Ov.img" to "boot.img" on my phone
11) i then used "ZArchiver" and compressed that "boot.img" i just renamed from "boot.img" to "boot.tar"
12) Copied the "boot.tar" file to my pc and renamed it to "boot.img.tar" on my pc
13) On PC i used "Odin3_v3.14.4" and flashed the "boot.img.tar" file to my device, i left "Auto reboot" and "F reset time" ticked
14) after flashing and getting the green "PASS" logo i left my phone pluged into the the pc the whole time while the phone was restarting
15) after phone rebooted i installed "Magisk" with the "Magisk_patched_for_A21S" app --> let it reboot again after install

AND THATS IT
ONE A21S SUCCESSFULLY ROOTED

How to root a217fxxs7cui3 on 7th bootloader??
Hello. Is it possible to root with android 11 binary 8?

Question Lost rooting Realme GT

Hi!,
I am trying to root my phone, I already unlocked fastboot and loaded TWRP. The main problem is that I try to extract with Python the boot.img from the firmware .ozip but I can't find the OZIP file, I just downloaded from realme page and some sites a firmware version with the .zip extension...
I tried to change it's extension to .ozip and then extract but there is no boot.img in the extracted file so I am a little bit lost right now.
On the other hand when I enter TWRP the touchscreen doesn't works and the phone always go to recovery when rebooted or fastboot when I press the - volume button.
What should I do..?
i dont know your version so im not sure which solution is better for you
if you wanna just make boot.img use just download your ROM from here and use payload dumper go from this post
if you wanna root directly this post will help you (just update the command from 24.3 to 25.2)
